Its matte and polished/bright finish adds a touch of sophistication, letting this watch shine in any setting. This model is also part of a limited series of 3,000 pieces worldwide, underscoring its exclusivity.
The dial of the Prospex Alpinist, in a stunning blue hue, is a true expression of classic watchmaking craftsmanship and modern innovation. Its brushed and matte finish creates a captivating interplay of light, enhancing the natural elegance of this timepiece. Arabic numerals ensure clear, distinct readability, complemented by luminescent hands and indices that guarantee perfect visibility even in low-light conditions. A date window cleverly positioned at 3 o'clock makes it easy to keep track of the date at a glance. The minute track around the dial underlines the precision and functionality of the display. Adding to its versatility, the watch features a built-in compass adjustable via the crown at 4 o'clock - an essential tool for modern explorers.
Powering this exceptional timepiece is a high-performance Japanese automatic movement, the Seiko caliber 6R35, produced by the prestigious Seiko Corp. This distinctive caliber boasts an impressive power reserve of 70 hours, ensuring the watch runs smoothly and accurately even after several days without being worn. The movement also reliably manages hours, minutes, seconds, and date functions, delivering optimized performance through its thoughtfully engineered architecture and robust construction.
The bovine leather strap features a highly realistic crocodile pattern, elevating the luxurious, classic appeal of this model. Its rich blue hue echoes the captivating tones of the dial, creating a visual harmony that's sure to turn heads. With a lug width of 20 mm, the strap fits most wrists comfortably for all-day wear. The single-fold deployment clasp makes putting on and removing the watch quick and secure. The watch also comes with a second strap in blue textile, offering a sleek option for more casual occasions or active environments.
With a water resistance of 20 ATM, this Seiko watch is fully equipped to keep up with a wide range of aquatic activities, from a relaxed poolside session to more technical dives. The combination of a screwed and transparent case back and a screwed-down crown provides superior protection against water, dust, and other elements, preserving the longevity and integrity of the movement inside. Whether you're swimming laps or pushing limits with scuba diving, this watch is engineered to handle demanding conditions without sacrificing an ounce of elegance.
